Clear selection

Black Ruthenium Tank Plating Solution plates a thin black layer on 18ct gold, sterling and Britannia silver.
Please note the maximum obtainable thickness of this process is 0.2 micron and abrasion resistance is an issue.
For longer lasting coatings, we recommend applying a clear lacquer after plating.
We recommend a coating thickness of 0.1 micron for black ruthenium.

Orders outside UK and EU

This plating solution cannot be purchased and shipped outside the UK and the EU because it’s part of our range of plating solutions which are regulated for transport.

Black Ruthenium Calculator

How to use this calculator :

1. In the first box, enter the thickness of black ruthenium (we recommend 0.1 micron).

2. In the second box, enter the surface area of the work that you are plating in square centimetres.

3. Click the ‘Calculate’ button.

4. Read off the amp setting, time it’s going to take and the volume of replenisher that will need to be added.


Notes:

  • When plating on nickel, copper and their alloys, a protective layer of at least 5 microns of silver should be plated followed by a gold flash layer (0.1 micron minimum) or a 18 karat rose gold layer prior to plating with black ruthenium.
  • When plating over 0.1 micron on electroplated gold, electroplated silver and fine silver, a brush-plated layer of 18 karat rose gold should be applied instead of the normal gold flash layer.
  • When plating on gold alloys between 9 and 18 karat and sterling silver, thicknesses of up to 0.2 micron of black ruthenium have been obtained.
  • For longer lasting coatings, we recommend applying a clear lacquer after plating.
  • We recommend that after use, the ruthenium plating solution is returned to its storage bottle in order to prolong the life of the mesh anode.
